TOPLINE: Mailed fecal immunochemical test (FIT) kits with reminder phone calls promote colorectal cancer (CRC) screening among veterans without recent primary care visits. Among 782 veterans in a randomized controlled trial (RCT), mailed FITs resulted in a 26.1% screening completion rate within 6 months, compared with 5.8% for usual care and 7.7% for mailed invitations with reminders. Improving screening in this population may help CRC morbidity and mortality among veterans.

METHODOLOGY

• Researchers conducted a 3-arm pragmatic RCT at the US Department of Verterans Affairs (VA) Corporal Michael J. Crescenz VA Medical Center (CMC-VAMC), enrolling veterans aged 50 to 75 years without a primary care visit within 18 months.

• Participants were randomized 1:1:1 to usual care (n = 260), mailed clinic-based screening invitation with reminder calls (n = 261), or mailed home FIT outreach plus prenotification letter and reminder phone calls (n = 261).

• Outcome measures included documented completion of CRC screening within 6 months after randomization in the electronic health record (EHR); a secondary outcome was FIT return within 6 months among those mailed FIT.

• Eligibility and exclusions were based on chart review and EHR criteria (eg, excluding symptoms, family history, inflammatory bowel disease, prior resection, or being current by having undergone a colonoscopy within 10 years, sigmoidoscopy or barium enema within 5 years, or fecal occult blood testing within 1 year).

TAKEAWAY

• CRC screening completion within 6 months is 26.1% with mailed FIT vs 5.8% with usual care (RD, 20.3%; 95% CI, 14.3%-26.3%; RR, 4.5; 95% CI, 2.7-7.7; P < .001).

• CRC screening completion within 6 months is 26.1% with mailed FIT vs 7.7% with mailed invitation plus reminders (RD, 18.4%; 95% CI, 12.2%-24.6%; RR, 3.4; 95% CI, 2.1-5.4; P < .001).

• Screening completion does not differ between mailed invitation plus reminders (7.7%) and usual care (5.8%), and the comparison is not statistically supported (RR, 1.3; P = .39).

• No statistically significant differences in screening completion are reported by age or race/ethnicity, and investigators also report no significant differences in FIT return by age or race/ethnicity in the secondary analysis.

 IN PRACTICE

“This research represents the first pragmatic RCT of mailed FIT outreach screening among veterans who have not recently (18 months) used primary care services offered by the VA. In this work, there were large relative, and absolute differences in CRC screening participation rate between veterans offered home FIT screening and those who received usual care (RR = 4.52, RD = 20.2%) or a mailed invitation plus reminders (RR = 3.40, RD = 18.4%)," wrote the authors.

SOURCE

The study was led by Matthew A. Goldshore, MD, PhD, MPH, of the CMC-VAMC . It was published online in Am J Prev Med.

LIMITATIONS

The study was not able identify differences in screening completion or FIT return by patient demographic characteristics such as age and race. The sample was randomized from predominantly male veterans cared for at a single VA medical center, limiting generalizability and reducing external validity. Follow-up and subsequent evaluation of FIT-positive participants is needed for the success of a mailed FIT intervention; of the 3 FIT-positive participants who should have received follow-up evaluation, only 1 underwent colonoscopy, highlighting the challenge of FIT to colonoscopy among participants who do not use care regularly at the CMC-VAMC.

DISCLOSURES

This trial received funding from an VA Health Services Research and Development Service award, with E. Carter Paulson, MD, MSCE, and Chyke A. Doubeni, MD, MPH, serving as principal investigators. Chyke A. Doubeni received support from grant number RO1CA 213645, and Shivan J. Mehta received support from grant number K08CA 234326, both from the National Cancer Institute of the National Institutes of Health. The authors reported no financial disclosures.

TOPLINE: 

A recalibrated environmental risk score for colorectal cancer (CRC) shows improved predictive performance in a study of 227,504 male veterans. The veteran-tailored score could help personalize screening better than previous models.

METHODOLOGY: 

• Demographic, lifestyle, and CRC data from 2011 to 2022 were abstracted from survey responses and health records of 227,504 male Million Veteran Program (MVP) participants, with complete data needed to construct the environmental risk score (e-Score).
• Researchers randomly split the male sample into 2 halves to produce training and validation samples (each n = 113,752; CRC cases n = 590) using simple random sampling with strata based on the CRC variable.
• Weighting for each environmental factor's effect size was recalculated using US Department of Veterans Affairs training data to create a recalibrated e-Score, which was compared with the original weighted e-Score in the validation sample.
• Analysis included nested multiple logistic regression models testing associations between quintiles for recalibrated and original e-Scores, with likelihood ratio tests used to compare model performance.
• Factors used to construct the e-Score included BMI, height, diabetes diagnosis, aspirin use, nonsteroidal anti-inflammatory drug use, educational attainment, physical activity level, smoking status, alcohol use, and dietary intake of fiber, calcium, folate, processed meats, red meat, fruits, vegetables, and total energy.

TAKEAWAY:

• The recalibrated e-Score showed a significant association with CRC, with higher quintiles indicating increased risk.
• In the validation sample, the recalibrated e-Score model significantly improved the base model performance (P < .001), while the original GECCO e-Score model did not show significant improvement (P = .07).
• The recalibrated e-Score model quintile 5 was associated with significantly higher odds for CRC compared with quintile 1 (odds ratio [OR], 1.79; 95% CI, 1.38-2.33; P for trend < .001).
• Black participants had higher odds for CRC compared with the White reference group across all models (base model OR, 1.46; 95% CI, 1.13-1.92; GECCO e-Score model OR, 1.44; 95% CI, 1.09-1.88; and recalibrated e-Score model OR, 1.38; 95% CI, 1.05-1.82).

IN PRACTICE:

"Despite the robust methods used in the work by the GECCO study upon which our study was based, an e-Score using their study’s weighting was not significantly associated with colorectal cancer among the male veteran sample. However, data from nearly a quarter million (n = 227,504) male US veteran participants of the MVP were used to recalibrate the e-Score to be veteran specific, and the recalibrated e-Score validation showed that it was significantly associated with colorectal cancer," wrote the authors of the study.

SOURCE:

The study was led by April R. Williams, US Department of Veterans Affairs Million Veteran Program Coordinating Center in Boston. It was published online in Cancer Epidemiology, Biomarkers & Prevention.

LIMITATIONS:

The study's limitations include potential recall and self-selection bias due to the use of self-reported data from the MVP. The generalizability of the findings may be limited to the veteran population, and the sample of Black veterans may have been insufficient for conclusive analysis. Additionally, the study did not include female participants due to insufficient data for a veteran-specific e-Score.
